Be itknown that 1, WILLIAM W. Asmara son, a citizen of'thc United States of Amer iea, and a resident of 'launton, in the county 'l'roin clothes after they have been washed or cleansed and subjected to the action of hydro extractors, and it consists in certain novel leatures of constructlon,arrangement and manner of operation, all as more fully.

hereinafter set forth and claimed. The o:.=ject 1 have in view is to produce a nmchine, or f wet wash drier, having a much greater d grecof efficiency than is possessed by other driers of this type heretofore devised.

My improved drying-machine is simple in construction; comparatively inexpensive to manufacture; economical in its 0 eration; not liable toget out of order; it is a apted to be readily and quickly charged with one or more independent washings or batches, and also as readily adaptable to discharge drying process, the several washes meanwhile being kept separated from one another whilethemachine 1s1n action, and then dis charged into'trucks or analogous receptacles having correspondingly separated compartmcnts. i

In a machine embodying my improye ments the attendant is enabled to perform his work with greater facility and rapidity and with much'less discomfort and inconvenience owing to the fact thatwhile thus performing the necessary manipulations or duties incident to the d ryin'g process he is not directly exposed to the comparatively high of Bristol and: State of Massachusetts, have them therefrom. after being subjected to the.

In the drawings the revoluble steam-heated, cylinderjor' drum A is r'ovidedwith hollow trunnions mounted in earings supported in the ends of the casing or housing B3 The cylinder is completely inclose'd within the casing chamber and surrounded by an ample space for the circulation of heated air. A suitable charging opening (I is formed in one side of the casing, a swinging door (Z serving to keep the opening normally closed or protected. in order to prevent to some extentthe escape of heated air from the casing chamber and also to protect the attendant while the door (1 is temporarily open, as for example when charging the cylinder with the wetwash or-material to be subjected to the drying process, the narrow longitudinally extending auxiliary door or partition 6 may be employed; this device when swung into the operative position, indicated in Fig. 3, then pr cticall closing the space lying between the eylin er and easing atthat pomt.

As drawn each end of the casing has a central opening. therethrough located below the drum to freely receive a truck or recep-- tacle 1) having an open top. Each receptacle has an outer flange adapted when properly positioned under the cylinder to completely:

close the opening and thus prevent the escape of hot air from the casing chamber at that point. The rear end of the casmg has two inlet-pipes oinozzles w' adapted to be connected to a blower for forcing air 1nto the casing chamber. Inorder to increase the tem erature of said air oppositely disposed auxi iary heatersor steam-heating coils D may belooated in the space lying between showirw the relation of the parts eorrespond- I to said arms a. SeeFig. 9.

i the said members p a'nd the corresponding.

side of the casing. The inlet end a of each coil is ada ted to connect with a suitable steamsupp y; the exhaust passing out at a",

form a chute or incline for insuring the proper;

' delivery of the dried wash'from the cylinder into the said receptacles p and also to provide means for more effectually diffusingor distributing the heated air throughout the casing chamber I employ oppositely located beveled perforated partitions 'or fixed screens ea These extend longitudinally of the machine and are disposed above said coils D and lie contiguous to the dryingcylinder A.. See Figs. 2 and 4. k The revoluble steam-heated c linder A is provided with two hollow annu ar heads. or end members a united together longitudinally of the machine by a series of suitably f spaced peripherally arranged parallel tubes gt, the-ends thereof-being secured to and in continuous open communication with the respective headsor hollow rings a. These 3.0 tubes constitute the walls or barrel proper of the cylinder and as drawn are secured 1n the inner sides of the members a. The hub of each trunn on is hollow, as before stated, and carries radiating arms or spokes a, the outer ends of the latter being secured to the sides of the respective members a. Steam-is conducted from aboiler or other suitable source a into the inlet-pipe 11, its lower end being cen- 'trally inserted and packed in the front trun- 40 nion in a well-known manner. When in use the steam passes freely and directly from the trunnion into the front head 41 via the connecting pipes t, Fig. 1, and after circulating throughit and throughthe tubes t it, as well 1 as the water of condensation, passes into the back head and its pipe connections i into the rear trunnion and escapes via outlet-pipe i The ends of the cylinder are protected or closed by means of sheet metal disks or 5 screensfll. so as to keep the wash or'material beingtreated from escaping from the end compartments. The screen may be secured be divided The interior of the cylinder may i 5 transverselyinto a plurality of compart- I ments by suitable partitions,- In the la'st-' named figure a portion of a central partition is indicated sectionally at u. Asthus ar-* ranged two compartments are pro'ducedpin the cylinder. Q I The'interior of the c linder is rendered readily accessible ,throug a suitable o ening (i produced by leaving out a nuzn er of the tubes 15 as clearl represented. This opening is keptnormal y closed or protected the guides -iipon the bolts.

by the freely slidable door 0 movable circumferentially 1n the two curved 5nd grooves 0 The door has a pair of handles or grips c for obvious urposes and located near its lower edge.,. ie'door is provided at or near'each end thereof with a lug or car Z-in which a horizontally disposed bolt 1" is slidably mounted. Saidbolt has a comparatively short endwise movement and :having its outer end 1" arranged to enter a recess 1" formed in the adjacent side of the head 0;.

Each bolt is resisted by a light spring 1), Fig.

9, and is attached to a chain or flexible connection h, in turn attached to a-vertically slidable block 9 supported in ways 7 located atthe center of the door. As thus constructed and arranged the two bolts of the closed door are adapted to be simultane-,

ously withdrawn or unlocked from the heads a .whenever-the'block 9 1s moved upwardly from its normal position a proper distance;

A collar 1* (Figs. Sand-4)? constitutes astop for limiting the rearward movement of the bolt. It maybe added that all the said members of the locking deinsure a direct endwisepu'll vice are mounted on the door c and rotate bodily and in unison with the cylinder. I- prefer to place the said handles below or in advance of the two alining bolts 1 with respect to the direction of rotation.

he cylinder remains stationary while it is belng charged and dischar ed. Fig. 3 re'presents it in the first-named osition, the doors (1 and c then being open, and Figs. 4, 7, 8 and 9 show the discharging position of the cylinder. In this position the opening (2 is'at the bottom and uncovered,'the casing door t n being closed. T

he following is a description of the means for mechanically unlocking and opening the door 0': A rock-shaft s is mounted at the left in theends-of the casing B and extends longitudinally thereof belowthe screen e. To

" the shaft is secured a central lever m adapt ed in use to contact with the underside of sa d block 9, and also two levers m arranged to engage; the handles a of the door. As drawn one end of the shaft extends outwardly through the front end of the casing and has secured. thereto an o crating lever 81 and quadrant member-.8 t re-lattersup porting a weight s. If desired stops or ading theangular movement of the shaftan'd its levers. See Fig. 5. The levers m and m- --inal-or dotted lineposition, Fig. 5, the slowly gusting screwsis maybeemployed fonliniiti revolving cylinder will first cause the block": 9 of the door '0 to engage the free end of the positioned lever m thus. arresting the slidable block 111 the guides f and withdrawing I the spring-pressed bolts r from the respective heads ,a," at substantially the same instant the ositioned leversj'm contactwith. the

hen es .0 of thedoor to hold the latter stationary, the cylinder continuing its movement until the o ening cl is full uncovered (Fig. 7),' followe by stopping t e machine.

If desired an arm or swinging shoe b may be employed'as a brake upon forcing it against the pe hery of'the'front head of the cylinder. T e brake action is controlled by a hand-wheel b secured to a suitably .mounted; screw bearing against the shoe. See Figs. 5 and 6.

and closing the doors 0 and d (the levels 8, m

and m then being in the lower or normal position, indicated -by dotted lines in Figs. 5

" and 2.

and 7) and starting the cylinder in motion. The driving means as drawn consists of suitable belt-driven pulleys and. gearing arranged inany well-known way. See Figs. 1 The action of the slowly revolving steam-heated cylinder in cooperation with air from the nozzles w, heatingcoils, D and screens-e produce a circulation-0f the heated air throughout-the casing chamber and through the interstices or continuously open narrow spaces formed between the tubes t or Wall of the cylinder. The moisture thus evaporated from the wash mingles with and charges the. air and passes from the casing chamber via outlet b in the form of vapor;

the result 'being' to produce'a more rapid,

thorough and uniform drying of the wash or material confined in the cylinder. This opera tion is succeeded by swingin the said levers upwardly to the full line position so as to lie in' the path of the members g and c of the then moving door 0; the conjoint action causing the bolts 1' to be withdrawn and the door to then remain temporarily stationary, the cylinder at thesame time continues its own movement until the opening (1 is fully uncovered and then sto ped; the wash may now fall therethrough lIy gravity into the receiver p positioned below it. Prior to restarting t 1e open cylinder the said levers are returned to the normal position, followed by turning it to and stopping it at the charging point, the casing door d meanwhile being opened and the partition b swung into place,

see Fig. :3. After introducing the wet-wash into the cylinder and returning member 6 to the normal position the door 0 is moved downwardly to its limit to close the opening (1 the bolts 1" at the same time springing into the registering bolt-holes 1'', thereby locking'the door, followed by closing the casing opening d by means of the outer door (1. The thus closed positions are indicated by dotted lines its barrel in Fig. 3. 1 Themachine is next set in operation and the moisture evaporated from the wash as before described.

It may be added that changes oi modifications in the construction of the machine may be made without departing from the spirit of the invention.

I claim as my invention and desire to se-- posed between in open communication with and connecting said heads and constituting the barrel proper of the cylinder, a charging opening formed in said barrel part, a door for normally closing said opening, means for rotating the cylinder, and means for intro- 'ducing steam into said heads and. tubes and discharging it therefrom.
